Esophageal varices seven days after banding, showing ulceration at the site of banding The upper two thirds of the esophagus are drained via the esophageal veins , which carry deoxygenated blood from the esophagus to the azygos vein , which in turn drains directly into the superior vena cava .
TIPS is a life-saving procedure in bleeding from esophageal or gastric varices. A randomized study showed that the survival is better if the procedure is done within 72 hours after bleeding. [2] TIPS has shown some promise for people with hepatorenal syndrome. [3] It may also help with ascites. [4]
Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
The esophageal branch of the left gastric vein drains into the azygos vein. In cases of portal hypertension, this communication allows for blood to bypass the portal vein and reach systemic circulation. As a result of this anastomosis, development of esophageal and paraesophageal varices is possible. [3]
The Sugiura procedure was originally developed to treat bleeding esophageal varices and consisted mainly of an esophagogastric devascularization. It was developed in Japan in 1973 [ 1 ] as a nonshunting technique that achieved variceal bleeding hemostasis by interrupting the variceal blood flow along the gastroesophageal junction.
Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. [1] Examples of varices include: [citation needed] Varicose veins, large tortuous veins usually found on legs; Sublingual varices; Esophageal varices, commonly stemming from cirrhosis of the liver, also known as oesophageal varicose

This is typically in addition to endoscopic banding or sclerotherapy for the varices. [21] If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. [21] If bleeding continues then balloon tamponade with a Sengstaken-Blakemore tube or Minnesota tube may be used in an attempt to mechanically compress ...
